I've just set up QNAP NAS server with runs Twonky media server to share media files. Music files plays fine, but video recordings (file type .ts from HUMAX cable box) get error not supported. I've been able to play same files from twonky with Samsung tv and in ps3 via PC.

So far I have:- Updated all relevant firmwares from QNAP and PS3- In mnt/HDA_ROOT/twonkymedia/resources edited clients.db and changed HH:PLAYSTATION -> PLAYSTATION 3
